When “warp” and “weft” yarns cross at 90-degree angles, the result is common cloth. But when small yarn loops reinforce each of those intersections, the result is a weft knit reinforcement fabric of uncommon strength and flexibility for critical reinforcement needs.


  • Adds reliable, low-cost strength to extruded products or backings
  • Stable without additional coatings or chemistries
  • Available in custom widths from 12 to 200 inches

Weft insertion was originally created for wall lining and curtain applications because of its superior strength, low cost and wide width capability. It soon replaced woven polyester as the material of choice for low-slope roofing products for the same reasons.

Most people are familiar with weft knit reinforced fabric even if they don’t know it by name—it’s the strength behind widely-used large party tent structures and your patio grill cover.
